Keeping Your Class 100 Cleanroom Actually Clean

When you’re running a Class 100 cleanroom, “almost clean” doesn’t cut it. One tiny flake of dust or a bit of outgassing from a heating element can wreck a semiconductor wafer or a medical implant in seconds. It’s a nightmare. That’s why we use high-purity quartz twin-tube lamps with a gold coating. It sounds fancy, but the reason is actually pretty simple.

Why the gold matters

Most infrared lamps just throw heat everywhere. It’s wasteful. We put a thin film of gold on the back of the quartz envelope to act like a mirror. Instead of heating up your machine frame—which does nothing for your product—the gold pushes all that IR radiation forward, right onto your workpiece. It basically doubles the heat hitting the target. And here is the best part: because the heat is so focused, you can run the lamps at lower temperatures and still get the same results. Your quartz lasts longer, and you don’t have to worry about materials breaking down from extreme heat.

On the fab floor, the photoresist bake isn’t a warm-up. It’s the gatekeeper for linewidth control. Let a 2°C drift show up across the wafer, and your critical dimensions move on you. Medium wave quartz heater tubes are built to stop that drift before it even gets started.

What matters, technically

Medium wave quartz emits in a band that couples cleanly into photoresist and polymer films, so you’re heating the film—not the chamber walls. The payoff is sub-millimeter thermal uniformity with repeatability you can count on. In production, that translates to ±0.1°C across the wafer at the bake surface, and setpoints that stay put lot after lot. Tube geometry and emissivity are tuned for a fast, controlled ramp and a repeatable soak, so your soft bake and hard bake profiles don’t drift between shifts.
